If your adventures are taking you to colder climes this season, you’ll need a heavyweight baselayer that can take the strain. The Arc’teryx Men’s Phase SV CZ Bottom is constructed from high performance Phasic fabric, which provides excellent moisture management, improves thermal regulation and incorporates silver ion technology to keep odour to a minimum. The seams are flat-locked throughout to reduce friction and chafing and there is a full crotch zip for convenience.
